CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 275,138, dated April 3, 1883,

Application filed January 17, 1883. (ModeL) To altwhom it may concern Be it known that I, NEWTON CAMPBELL, of Elizabethtown, in the county of Hamilton and State of Ohio, have invented certain-new and useful Ilnprovementsin Self-Couplers for Cars;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, referencebeing had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in self-couplers for cars; and it consists in the combination of a draw-head, having a slot through its top, with suitable guiding-standards, a perforated plate which moves vertically upon the standards and which carries the coupling-pin with it, and a supporting-rod which is attached to the plate for the purpose of holding it raised upward, ready for the cars to couple when they run together, as will be more fully described hereinafter.

The object of my invention is to provide an automatic coupler for cars, so that the cars will couple when they run together, and thus do away with all necessity of brakemen risking their lives and limbs by going in between the cars.

Figures 1 and 2 are vertical sections of my invention, taken at right angles to each other.

A represents an ordinary draw-head, which has a slot,B, cut through its top. Secured upon the top of this draw-head are the two guides or standards 0, which may either be formed in a single piece, as shown, or they may be formed separately and attached to opposite sides of the draw-head in any suitable manner. The upper ends of these guides will be preferably made screw-threaded and receive a not upon them, which nuts act as stops to prevent the plate D, which moves vertically upon the guides, from becoming displaced.

The plate has the coupling-pin G passed down through it, and the plate carries the pin up and down with itin all ofits movements. Also secured to this vertically-moving plate or casting is the supporting-rod. I, which is loosely attached to the under side of the plate, and which has its lower end bent so as to slide freely upon the bottom of the draw-head. When the plate is raised upward this supporting-rod automatically catches against the bottom of the draw;head and forms a support, so as to hold the plate or casting in a vertical position. The plate or casting remains in this elevated position until the couplinglink from the other car enters the draw-head, strikes against the lower end of the rod, and forces it backward, when the plate or casting instantly drops downward and the couplingpin passes through the link, so as to bind the two cars together. The part to which the supporting-rod is fastened forms a ring or handhold upon the top of the plate or casting, so that the plate can have a rod or chain attached to it and be readily operated from the platform of the car, the top of the car, or from any other placed desired.

Having thus described claim- The combination of the draw-head having the slot B through its top, the guides O, the vertically-moving plate carrying the couplingpin, and the supporting-rod which is attached to the under side of the plate for the purpose of holding the plate and pin in a raised position, ready for the cars to couple, substantially as shown and described.

In testimony whereof Iafiix my signature in presence of two witnesses.

NEWTON CAMPBELL.
